CONDUCTIVE BRUSHES
Characteristics:
• Brushes minimize static charge generation and remove electrostatic charges to ground
when held by grounded personnel
• Dissipative polypropylene black handles remove charges when grounded
• Available in two kinds of bristles - semi fine, firm
• Semi-fine bristles are ideal for chemical and electronics applications
• Firm bristles are mainly for electronics, especially circuit boards
• Conductive handle’s ESD properties are not effected by humidity as are wooden handle
brushes
• Conductive copper based nylon bristles with hog hair and two other natural fibers.
• RTT Resistance: 1 x 10
3
to <1 x 10
5
ohms tested per modified ANSI/ESD S4.1
Materials:
• Firm bristles - conductive yarn and pig hair
• Semi-fine bristles - conductive yarn and horse hair

Synthetic vs. Natural Bristles
Synthetic bristles can easily become charged with static in standard humidity conditions.
Natural hair usually builds static in areas of low humidity, but due to the conductive fibers in our brushes,
this problem does not take effect.
Generally speaking, once the conductive yarn is added to the bristles, it neutralizes the possibility of static
build up caused by the natural hair.

Dimensions are taken from the bottom of the brush to the top of the bristles.
Designed to fulfill ANSI/ESD S20.20 requirement to ground all conductors
at ESD workstation.
ESD Handbook TR20.20 Table 1 lists under Typical Static Electricity Sources
“Brushes (camel/pig hair and synthetic bristles).”
“It should be understood that any object, item, material or person could be a
source of static electricity in the work environment. Removal of unnecessary
nonconductors, replacing nonconductive materials with dissipative or conductive
materials and grounding all conductors are the principle methods of controlling
static electricity in the workplace, regardless of the activity.” (TR 20.20 section
2.4)
